LAVATORY-FITTING.

Specification of Letters Patent.

Patented Nov. 17, 1914.

Application filed May 7, 1914. Serial No. 836,860.

ware have invented certain new and useful Improvements in Lavatory-Fittings, of which the following is a true and exact description, reference being bad to the accompanying drawings, which form a part thereof.

My present invention consists in an improved fitting especially devised and adapted to be inserted in an aperture in a lavatory basin slab, and formed with a passage adapted to receive a tubular waste valve, and with a mixing chamber for hot and cold water and with a delivery spout opening therefrom above the basin slab when the fittin is in place, and havingprovisions by which hot'and' cold water supply pipes'may be secured to the fitting' in communication with. said mixing chamber beneath the basin slab.

The object of my invention, considered in one of its aspects, is'to provide a simple and compact fitting of the character specified above, which isadapted to be inserted in a basin slab orifice not greatly exceeding in diameter the diameter of the tubular waste valve passa'ge'provided in'the fitting.

More specifically, the object of my inven tion is to provide a satisfactory onepiece fitting of the general character specified, having awaste valve passage adapted to receive a tubular waste valve of the usual size, while the fitting as awhole. is of suchsize and form that it may be inserted in the central aperture of a standard form of basin slab having three apertures ofthe size, shape and arrangement commonly employed with separate hot and cold water supply valves mounted in the side apertures and each provided with an independent discharge spout located above the basin slab, and with the central aperture receiving a fitting, the sole purpose of which is to provide a suitable housing for a tubular waste valve. My improved combination mixing nozzle and waste valve fitting thus permits a standard basin slab to be fitted without any change in the slab structure with two difierent types of fittings, and thereby permits plumbers and plumbing supply houses to reduce the amount of stock kept on hand without correspondingly diminishing the different styles of-apparat'us.

The various features of novelty pharacterizing my invention'are pointed out with particularity in -the claims annexed to and forming a part of this specification. Fora better understanding of'the invention, however, and of the advantages po'ssessed'by it, reference should be had'to the accompany-j ing drawings and descriptive matter in which I have illustrated and described a preferred form in which my invention may be embodied.

Of the drawings: Figure 1 is a plan of a basinslab equipped with my improved fittings; Fig. 2 is an elevation,rpartly' in section, on the line 2-2 of Fig. 1;'Fig. 3 is a partial section on the line 3 3 of Fig. 5;;

Fig. i is a sectional plan taken on the. line 4% of Fig. 3; and Fig. 5 isa section taken on the line 5-5 of Fig. 2.. f

In the drawings, A- .represents'"' the slab and A the bowl of a: lavatory basin fixtureof common form. Thi's'slabis formedwith a central aperture Ar and two sid'e apertures. The cold water supply valve Efisflmounted in one, and the, hot water supplyvalve E is mounted in the otherside aperture' These 2 valves do not have discharge spouts above the..

basin slab but, on the contrary, have their discharge \PIPQS D connectedtojthe mixing chamber B of the centralffitting B, which passes through the central slab aperture A. i

The central. fitting B, as shown, is formed with a head portion B" above the slab, and larger in diameter than the aperture'Afl and engaging the upper surface of the slab at the margin of the-aperture A The body portion of the fitting B immediately beneath the head B is cylindrical and is externally threaded to receive the nut C by which the fitting is clamped in place. The mixing chamber B' is shaped with a view of insuring a mixing chamber of ample size along side of the passage B provided for a tubular waste valve F of the usual form and size. As shown the mixing chamber B is arc-shaped in horizontal cross section. A delivery spout B projecting from the head B passes water from the mixing chamber B to the basin bowl A. Beneath the slab A the fitting B is formed with threaded bosses B to which the ends of the pipes D are connected. Advantageously, as shown, the threaded bosses B have their centers well to the rear of the center line of the waste valve passage B, as this facilitates the connection of. the pipes D thereto. The fitting B is a one piece structure, preferably in the form of an. integral casting."

As shown, the wall surrounding the passage B is internally threaded at its lower end to receive the upper end of a tubular part G which is connected to a casing H. The latter is connected at its side to the outlet orifice A in the bottom of the basin bowl by the pipe I. At its lower end the casing H is'connected to the waste pipe J by a port surrounded at its upper end-by the seat H for the waste valve F. The internal diameter of easing H and of the tubular part G is appreciably greater than the external diameter of the waste valv'e'F to permit the wate'rto pass from the bowl A to the overflow port s F in the hollow valve F when the maximum height of water level in the bowl is reached. The body of the fitting B is reduced in diameter between its thread ed upper end portion and its lower end, and

' the corresponding portion of the mixing chamber B may be regarded as located in a hollow rib-like projection from the outer wall of this cylindrical guide.

It will be apparent to those skilled in the art that the construction disclosed herein is exceedingly simple and effective. The lower end of the fittin B may be readily threaded through a basin slab orifice A of the usual size and shape provided for a plain tubular waste valve fitting, While at the same time the passage 13 is adapted to receive a waste valve F of the usual size, and. the mixing chamber B is of ample cros'ssection. The reduction in diameter of "the body portion of the fitting B between its ends facilitates the passage of the enlarged lower end of the fitting through the r fice A and the pa s ge of e clamping Put O t he. b dy por on of t e fitting,

Ha ing ow de ribed, my inven i n, Wha I claim as new and desire to secure by Letters Patent, is;

1. combination one pie e mixing nozzle Copies of this patent may he obtained for and waste valve fitting comprising, a tubular body enlarged at one end to form a head adapted to seat against a support at the margin of an aperture in the latter receiving said tubular body and having a delivery spout projecting from said head at one side, said tubular body comprising a cylindrical portion adjacent said head externally threaded to receive a clamping nut, said fitting being formed with a waste valve passage extending through said head and body and with a mixing chamber arc-shaped in cross section and partially surroundingsaid passage, said ing at its upper end with said delivery spout and said tubular body being formed adjacent its end remote from said head with provisions for securing two supply pipes thereto in communication with said mixing chamber.

2. A combination one-piece mixing nozzle and waste valve fitting comprising a tubular body enlarged at one end to form a head adapted to seat against a support at the margin of an aperture in the latter receiving said tubular body and having a delivery spout projecting from said head at one side, said tubular body comprising a cylindrical portion adjacent said head externally threaded to receive a clamping nut, said fitting being formed with a waste valve passage extending through Said head and body and with a mixing chamber arc-shaped in cross section and partially surrounding said passage, said mixing chamber communicating at its upper end with said delivery spout and said tubular body being formed adjacent its end remote from said head with two hollow arms through which two supply pipes may be placed in communication with said mixing chamber and being reduced in diameter between said threaded portion and said arms.
